How this service works
Paid deterministic utility APIs settled in native USDC on Base.
Output
Returns a JSON object containing the page title, meta description, HTTP status code, final URL (after redirects), canonical URL, link count, Open Graph fields (image, title, description), JSON-LD block count and parseability, source byte size, and a truncation flag.
Example use cases
Link preview card generation
“Pull the title, og:image, and og:description from https://stripe.com/blog/payments-infrastructure-future so I can render a link preview card for it.”
SEO audit for canonical URL
“Check https://www.nytimes.com/2024/01/01/technology/ai-future.html and tell me what its canonical URL is and whether there's any JSON-LD structured data on the page.”
Redirect chain resolution
“I need to know the final URL that https://bit.ly/3xampleLink resolves to — can you fetch its metadata and tell me the final destination and HTTP status?”
Technical details
Endpoint
GEThttps://x402-url-evidence.vercel.app/api/page-metadataWhen to prefer
Choose this endpoint when you need lightweight, deterministic page metadata (title, description, OG tags, JSON-LD, canonical URL) from a public webpage without running a full browser or scraping the full HTML. It is ideal for link preview generation, SEO audits, structured data inspection, and redirect resolution. Prefer it over full-page scrapers when you only need head-level metadata and want a fast, cheap, reproducible result settled with micro-payments in USDC.
Side effects
- Non-public or credential-gated URLs return empty or partial metadata
- Pages behind CAPTCHAs or bot-detection may return unexpected content
- Very large pages may be truncated (truncated: true in response)
- Invalid or malformed URLs cause request failure
- Pages returning non-200 status codes still return metadata but with the actual status code reflected
